Patent KR-20000068401-A (KR)
IPC: D21F11/00
Filed: 1997-08-28
Abstract: A papermaking vacuum apparatus having a web-facing surface (114) adapted to support a papermaking belt (11) and comprising a head (110), a body (120) and at least one vacuum slot (116) disposed in the head and defining an aperture (118) on the web-facing surface. The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The web-facing surface comprises a textured (115) area in the region of the web-facing surface juxtaposed with the aperture defined by the vacuum slot. This textured area creates a leakage of at least about 35 Marlatts at a pressure differential of 17,5 cm (7 inches) of Mercury. This leakage eliminates the vacuum seal between a smooth backside of the papermaking belt and the web-facing surface of the vacuum apparatus.
